  1. IIMK’s Experience with Greenstone in Building Digital Library Collections Dr. M.G. Sreekumar Centre for Development of Digital Libraries (CDDL) Indian Institute of Management Kozhikode (IIMK)

  2. Digital Libraries

  3. Gateway-out Data capture Internet / Intranet Multimedia Library Info System USER @ anywhere (access to information from anywhere)

  4. Organizational Transformation in Libraries • Traditional / Automated • Organization is physical • Shelving of documents - Based on Subject Cln • Key - Index / Catalogues / Cards / Digital Catalgs • Cards - Real/Virtual - Author, Title, Descriptions • Digital • Organization in terms of digital files /objects • Contains material digitized form • Contains digital material • Architecture • Key - Metadata

  5. Features of Digital Libraries… • Dynamic Electronic Information Systems • Seamless Aggregation and Integration of Scholarly Content • Create / Maintain Local Content • Strengthens - mechanisms and capacity - Information Systems / Services • Increase Portability • Efficiency of Access • Flexibility • Availability • Long term preservation UNESCO

  6. Digital Library Technologies • Open architectures (Open DLs) • Componentized vs Monolithic systems • Interoperability (role of Z39.50, OAI etc.) • Unified interface for heterogeneous libraries • Metadata mapping across different libraries • OAI-compliant data and service providers • Multilingual digital libraries • Scalable digital library architectures • Publication tools • Searching tools

  7. Software Selection • Goals and Requirement Specification • Proprietary Vs Open Source • Fit the existing Information System • Accommodate future migration • Embrace all possible/predominant formats • Support standard DL technologies/platforms • Easy installation, population, maintenance • Comprehensive Documentation • Software Development Team • Active User Groups, E-Mail Lists (Users / Developers)

  8. What are digital libraries for? • Knowledge/content management • Manage and access internal information assets • Scholarly communication, education, research • E-journals, e-prints, e-books, data sets, e-learning • Access to cultural collections • Cultural, heritage, historical & special collections, museums, biodiversity • E-governance • Improved access to government policies, plans, procedures, rules and regulations • Archiving and preservation • Many more …

  9. DL Software: Alternatives • What are your expectations? • Develop local web-based application? • Commercial DL solution? • Adopt open source software? • Greenstone • Eprints • DSpace • (CDS/ISIS, Koha)

  10. Dublin Core Metadata Initiative Metadata Definition The Basics: 22 Elements Title The name given to the resource by the creator or publisher Creator The person responsible for the intellectual content of the resource Subject The Topic of the resourceDescription A textual description of the content of the source Publisher The Entity responsible for making the resource available Contributor A person or organization (other than the Creator) who is responsible for making significant contributions to the intellectual content of the resource Date A date associated with the creation or availability of the resource Type The nature or genre of the content of the resource Format The physical or digital manifestation of the resource Identifier An unambiguous reference that uniquely identifies the resource within a given context Source A reference to a second resource from which the present resource is derived Language The language of the intellectual content of the resource Relation A reference to a related resource, and the nature of its relationship Coverage Spatial locations and temporal durations characteristic of the content of the resource Rights Information about rights held in the resource Content Responsibility Manifestation

  11. Greenstone DL Software Overview of Features, Capabilities & Applications

  12. What is theGreenstone software? • Software suite for building, maintaining, and distributing digital library collections • Comprehensive, open-source • Developed by New Zealand Digital Library Project at the University of Waikato • Distribution and promotion partners: • UNESCO • Human Info NGO, Belgium • NCSI, Bangalore; UCT, Cape Town;Dakar, Senegal; Almaty, Kazakhstan; … • You!

  13. Greenstone Features contd... • Easy Installation • Easy Maintenance • Content Development (3 alternate ways) • Predominantly GLI now - since (V. 2.41) • Hierarchy Structure • Interface Customization • Front Page Design, Header for the Digital Library, Collection Icon, Cover Images • Collection Configuration (Collect.cfg) File • Scalability, Flexibility • Interoperability (Crosswalk), OAI Compliance • Lifeline : Listserv / E-Group / Archives

  14. GLI Functions • Establish new collection (or work on old) • Select files to include in collection (Gather) • Enrich files with metadata (Enrich) • Select Plugins, Indexes, Classifiers (Design) • Build Collection (Create) • Customize Appearance • Preview Collection

  15. Create a new collection

  16. Create: Build the collection

  17. Preview: admire the result

  18. Customization • Greenstone is specifically designed to be highly extensible and customizable. • New document and metadata formats are accommodated by writing "plugins" (in Perl). • Analogously, new metadata browsing structures can be implemented by writing "classifiers." • The user interface look-and-feel can be altered using "macros" written in a simple macro language. • A Corba protocol allows agents (e.g. in Java) to use all the facilities associated with document collections. • Finally, the source code, in C++ and Perl, is available and accessible for modification

  19. Customizing with macros • let you customize presentation • present pages in different languages • print variables into the page text(e.g. number of search hits) • Macro files • stored in gsdl/macros folder • each file defines one or more “packages” • (A “package” is a group of macros) • loaded on startup(note difference between Local and Web Library) • listed in etc/main.cfg • Collection-specific macros • Stored in gsdl/collect/mycol/macros/extra.dm • Or include argument [c=collectionname] for each macro

  20. Personalizing your home page C:\Program Files\gsdl\etc\main.cfg change home.dm to yourhome.dm
